Lane M: 100 bp DNA Marker, 1-3: Representative S. aureus isolates, 4: Positive control, 5: Negative control. (b) PCR amplification of tetA gene of tetracycline-resistant Salmonella spp. Lane M: 100 bp DNA Marker, 1-4: Representative Salmonella spp. isolates, 5: Positive control, 6: Negative control. (c) PCR amplification of tetB gene of tetracycline-resistant Salmonella spp. Lane M: 100 bp DNA Marker, 1-5: Representative Salmonella spp. isolates, 6: Positive control, 7: Negative control. (d) PCR amplification of mcr3 gene of colistin-resistant E. coli. Lane M: 100 bp DNA Marker, 1-4: Representative E. coli isolates, 5: Positive control, 6: Negative control.
